Chemical Structure

(4R,5R)-rel-5-hydroxy-4,6-dimethylheptan-3-one CAS 71699-34-8 chemical structure

Description

The molecular framework of (4R,5R)-rel-5-hydroxy-4,6-dimethylheptan-3-one (C8H6O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

(4R,5R)-rel-5-hydroxy-4,6-dimethylheptan-3-one (CAS 71699-34-8), molecular formula C8H6O2 and molecular weight 134.13 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
